In VBA, an assignment of variables of type Object is a shallow copy, an assignment for all other types (numeric types, String, user defined types, arrays) is a deep copy. So the keyword Set for an assignment signals a shallow copy and the (optional) keyword Let signals a deep copy. There is no built-in method for deep copies of Objects in VBA.
In computing based on the Java Platform, JavaBeans is a technology developed by Sun Microsystems and released in 1996, as part of JDK 1.1.. The 'beans' of JavaBeans are classes that encapsulate one or more objects into a single standardized object (the bean).
The default implementation of Object.clone() performs a shallow copy. When a class desires a deep copy or some other custom behavior, they must implement that in their own clone() method after they obtain the copy from the superclass. The syntax for calling clone in Java is (assuming obj is a variable of a class type that has a public clone ...
Copy-and-paste programming, sometimes referred to as just pasting, is the production of highly repetitive computer programming code, as produced by copy and paste operations. It is primarily a pejorative term; those who use the term are often implying a lack of programming competence and ability to create abstractions.
For example, due to the nature of Java, the IDL-Java mapping is rather straightforward and makes usage of CORBA very simple in a Java application. This is also true of the IDL to Python mapping. The C++ mapping requires the programmer to learn datatypes that predate the C++ Standard Template Library (STL).
Objects containing confidential data (e.g. a user's credit card numbers) must be cleared before being passed to new clients, otherwise, the data may be disclosed to an unauthorized party. If the pool is used by multiple threads, it may need the means to prevent parallel threads from trying to reuse the same object in parallel.
In object-oriented programming, the factory method pattern is a design pattern that uses factory methods to deal with the problem of creating objects without having to specify their exact classes. Rather than by calling a constructor , this is accomplished by invoking a factory method to create an object.
An example of an EJB bean being a POJO: Enterprise JavaBeans (EJB), Java Persistence API (JPA) (including Hibernate) CDI (Contexts and Dependency Injection for the Java EE platform) The following shows a fully functional EJB bean, demonstrating how EJB3 leverages the POJO model:
